While shagging a girl doggy-style, place your thumbs in either side of her mouth with your fingers pointing up like antlers.
I gave her a good stagging last night. You've been stagged. Her head would look good on my wall.

The act of traveling back in time for the sole purpose of having indulgent sex with yourself.
I'll bet Doctor Who invented Stagging so he wouldn't need a sidekick.
